Upon examining the archive, lots of cut content can be found on the development discs that isn't in the final game, nor its prototypes, along with some other weird stuff. The game's pre-rendered sprites and levels were made in Discreet 3D Studio Max, and can easily be opened in any version. At one point, all of the characters were meant to be pre-rendered 3D, but were changed to 2D sprites in the final game, which would explain the visual inconsistencies. The only model that wasn't used in any build, minus early prototypes of the Game Boy Advance game.
